XML::DOM::DOMImplementation - Information about XML::DOM implementation
The DOMImplementation interface provides a number of methods for performing operations that are independent of any particular instance of the document object model.
The DOM Level 1 does not specify a way of creating a document instance, and hence document creation is an operation specific to an implementation. Future Levels of the DOM specification are expected to provide methods for creating documents directly.
Returns 1 if and only if feature equals "XML" and version equals "1.0".
